ABSTRACT:
An image processing system includes a local area selecting section configured to select a local area as at least one correction target from an input image, the local area including at least one pixel; a correction amount calculating section configured to calculate a gradation correction amount for the local area as the correction target; and a local gradation correcting section configured to perform a gradation correction to correct a gradation value of the local area based on the gradation correction amount to generate an image with a local gradation correction. Also, the correction amount calculating section includes a peripheral area gradation value calculating section configured to calculate a gradation value of a peripheral area of the local area; and a local area correction amount converting section configured to calculate the gradation correction amount by using the calculated gradation value of the peripheral area.
